Weight lifting program apps: what you're actually buying

Search for a weight lifting app and you get a list of things that have almost nothing in common. Some cost nothing. Some cost more than a gym membership. The reviews don't help, because people are rating completely different products against completely different expectations — and half of them are annoyed about a feature the app was never trying to have.

There's one question that sorts the whole category.

Three things called "apps"

1. Trackers

You bring the program. The app writes it down.

You choose the lift, the weight and the sets. It stores them and shows you the history. Most are free or nearly free, and the good ones are genuinely good at this — clean logging, fast entry, a chart of what you've lifted over time.

The tell: you open it and it's empty until you fill it.

If you already know what you're doing, a tracker may be all you need. Plenty of strong people have never used anything else. The problem is that most people searching for a "program app" end up with one of these, then conclude that apps don't work — when what actually happened is that they bought a notebook and expected a coach.

2. Program libraries

The app contains programs. You pick one from a menu — a twelve-week strength block, a push-pull-legs split, a beginner template — and follow it.

This is a real step up from nothing, and for a straightforward goal it can work well. But the program was written before anyone knew you existed. It doesn't know your gym, your history, what you can't do yet, or what happened last Tuesday.

The tell: you choose the program yourself, from a list.

3. Coached programming

Someone writes the program. It updates from what you actually lifted. A human looks at your numbers.

This costs more, because there's a person in it. That's the whole difference in price, and it's worth knowing that's what you're paying for.

The tell: you open it and today's session is already there — and it's different from last week's because of what you did last week.

Six questions that separate them

Whatever the marketing says, these are answerable before you pay. If most of them come back no, you have a tracker with a workout menu attached.

• Does the weight change based on what you lifted last time? This is the whole mechanism. Progressive overload is just asking for slightly more than you comfortably have, often enough that your body stops treating it as unusual. An app showing the same numbers in week six that it showed in week one isn't programming — it's a reminder.
• Does it tell you how long to rest? Rest is a programmed variable, not a break. Five minutes between heavy sets does something different from ninety seconds, and an app that leaves it to you has left out part of the workout.
• Does the program change every few weeks? A load and a rep range that never move stop teaching after about a month. Something has to cycle.
• Are there substitutions built in? Your gym doesn't have a safety squat bar. The leg press is taken. Your shoulder won't go overhead today. A real program has the alternative already there, matching the movement pattern — so you're not improvising at the rack.
• Can you actually run it at your gym? Programs written around equipment you don't have become programs you don't follow.
• Does a human ever look at it? Not "is there a chat button." Does anyone see your logged numbers and change something because of them.

What about AI programming?

Worth being fair about this, because it's where most of the category is heading.

An algorithm handles progression arithmetic well. Better than most people do by hand, honestly — it won't forget what you lifted, it won't get optimistic on a Monday, and it'll adjust the numbers consistently. For the maths of getting slightly heavier over time, it's a good tool.

What it can't do is see you. It doesn't know your bar path drifted on the third rep, that you stopped bracing when you got tired, or that you've quietly been avoiding one lift for a month. It reads the numbers you typed, and the numbers you typed don't contain any of that.

So the question isn't whether the programming is generated or written. It's whether anybody is ever looking.

What it costs, and why

Price won't tell you quality, but it does tell you which of the three you're buying.

Trackers are free or a few dollars because there's no ongoing cost to serve you. Program libraries sit in the middle — the programs were written once and sold many times, which is a reasonable business and a reasonable price. Coaching costs more because someone's hours are in it, and hours don't get cheaper at scale.

If an app promises individual coaching at tracker prices, work out where the hours are coming from. Usually they aren't.

How to choose, in one paragraph

If you know how to program and just want to log it, get a tracker and stop reading reviews. If you want a sensible plan and you're happy to adapt it yourself, a program library is good value. If you've already tried both and stalled — which is why most people start searching in the first place — the thing that was missing wasn't an app. It was someone deciding what you should do next, based on what you actually did.

If you're starting from further back than that, strength training for women over 50 covers how to set this up from the beginning, whatever you end up running it on.
